New Cefiderocol 30 μg disk


Cefiderocol is a siderophore cephalosporin with a unique mechanism for penetrating efficiently into Gram-negative pathogens.
Cefiderocol binds to free iron and is actively transported into bacterial cells through the outer membrane.
This Trojan horse strategy allows cefiderocol to enter the space in-between the bacterial cell walls and disrupt cell wall synthesis. In addition, cefiderocol is stable against nearly all beta-lactamases, including both the serine and metallo-carbapenemases.

Disk diffusion breakpoints for cefiderocol are available for Enterobacteriaceae, P. aeruginosa, A. baumannii and S. maltophilia.

Lockable contact plates

Septic environments and critical controlled manufacturing areas require maximum security after collecting samples. The new lockable contact plates by Liofilchem avoid contamination by accidental opening of contact plates during the sampling process, handling and transportation.The secure plate lock is obtainable with one hand only, through a gentle base-lid pressure, confirmed by a clear click sound.
